To all whom it may concern:

Be it known that I, OROENITH F. ALLEN, a citizen of the United States, residing at Temple, in the county of Bell and State of Texas, have invented a new and useful Buckle, of which the following'is a specification. f p

This invention relates to buckles, and more particularly to devices of thatclass in which the two ends of the independent, flexible elementtransmitting the tensile stress are clasped together by the transverse pressure of a cam.

It is the aim of this invention to provide in a merchantable and inexpensive form, a buckle which shall perform its ofiice quickly,- positively and without mutilation of the parts upon which it exercises its function.

With these and other objects in view, as will hereinafter more fully appear, the invention consists in the novel construction and arrangement ,of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 i ward at right angles-to the part Ato form,

the lateral supports for the strap-end C. Superimposed upon the base portion A and parallel thereto, is the member D, having its sides, E, bent downward at right angles to the part D to form a lateral support for the strap-end F, the ends, G, of the member D being prolonged beyond the ends of the part E. Upon the part D and slightly inset from its edges, are the ears H, through which passes the axle I upon which is suspended so as to be rotatable through a determinate arc, the cam J. Attached to the member D, preferably by the rivet K, is the resilient cam rocking member L, brushing with a slight pressure upon the cam J and serving to force it quickly to a firm bearing upon the strap end F. It is to be under stood that in the completed device, the parts A, D and H are firmly united by soldering, clenching or other method adapted to that end; or they may be fashioned integrally, Wholly or in part.

The cam J may be of any form;ipreferably, however, as shown, it is substantially ovate-oblong in cross section, this form having been selected as one adapted to attain its position of maximum efficiency with a minimum of lost motion. The axle I is so placed in the cam J that the center of gravity of the cam is below the line of.

suspension, the end P projecting to form a thumb-lever as hereinloefore described. The bearing surface of the cam J is preferably smooth, that no injurymay be inflicted upon the upper or dressed side of the strap F.

The device may be permanently attached to the strap-end C by any of the conventional methods of the art. As shown, it is retained in position by the rivets M, which .are passed through the apertures N and brought to a bearing contact by malleation. That portion 0 of the member A which is beneath the bearing surface of the cam J .is provided with transverse teeth Q, one of the terminal ones of which is longer than the remaining ones in order to form a kink or bend in the strap end C and thus accentuate the gripping action of the cam. will .be understood, the teeth referred to engage with the lower or pelt side of the strap end F, as clearly shown in Fig. 3.

In practical operation, the strap-end F is thrust between the cam J and the base member A and drawn tight, being retained against withdrawal by the pressure of the cam J and the friction of the surface 0. When it is desired to release the strap, a slight pull upon the protruding end, will loosen the cam J whereupon it may be held clear by thumb pressure upon the end P, and the strap withdrawn.

What is claimed is 2- 1." A buckle comprising a base plate provided with lateral strap supports, a top plate provided with lateral strap supports, ears carried by the latter plate, an axle rotatably mounted in the cars, a cam carried by the axle, and a spring having one end secured to the top plate and its other end disposed upon the cam.
